Description
Air fryer crispy onions are a delicious and healthy alternative to deep-fried onions. They are golden, crunchy, and flavorful, perfect for topping casseroles, burgers, salads, or as a snack.
Ingredients
Scale
- 1 large yellow or sweet onion, thinly sliced
- 1/2 cup buttermilk
- 1/2 cup all-purpose flour
- 1/4 cup cornstarch
- 1/2 teaspoon garlic powder
- 1/2 teaspoon smoked paprika
- Salt and pepper to taste
- Olive oil spray
Instructions
- Place the sliced onions in a bowl and pour the buttermilk over them. Toss to coat and let them soak for 15 to 30 minutes.
- In a separate bowl, whisk together the flour, cornstarch, garlic powder, paprika, salt, and pepper.
- Remove the onions from the buttermilk, allowing excess to drip off, and dredge them in the flour mixture until well coated.
- Lightly spray the air fryer basket with olive oil spray.
- Place the coated onions in a single layer in the basket. Work in batches if needed to avoid overcrowding.
- Spray the tops of the onions lightly with oil and air fry at 350°F for 10 to 12 minutes, shaking the basket halfway through, until golden and crispy.
- Let them cool slightly before using. They will continue to crisp up a bit as they cool.
Notes
- Use a mandoline or very sharp knife for evenly thin onion slices, which ensures they cook and crisp evenly.
- If you don’t have buttermilk, you can make a quick substitute by mixing 1/2 cup milk with 1 teaspoon vinegar or lemon juice and letting it sit for 5 minutes.
- Store any leftovers in an airtight container at room temperature for up to 2 days. Re-crisp in the air fryer for a few minutes if needed.
- Perfect for topping green bean casserole, mashed potatoes, or any dish that could use a savory crunch.
